To cZZ whom it may concern:

lie it known that I, lVIAXIMILLAN Knainnn, a citizen of the United States, anda resident of Brooklyn, county of Kings, State 01' l*lew liork, have invented certain new and lapse of time between the exposure of each picture of the series being preferably pro vided for.

One of the objects of my invention is to produce a device of this kind which is simple in construction and permits a coiuparatively great number of slides or picture plates to be exposed within a compact structure; another object of my invention is to provide novel auxiliary mechanisms whereby motion may be imparted to an exposed slide, such motion being either a rotary motion or an oscillating or rocking motion. my construction being adapted to combining in one device the means for obtaining either one of such motions or both of such motions for an exposed slide or plate.

Further objects and improvements con templated by my invention hereinafter appear from my description and from the accompanying drawings wherein Figure 1 illustrates a side elevation indicating more particularly the manner of nmunting the various rotating parts;

Fig. 2' represents a plan view thereof;

Fig. "8 represents a detail view, in elevation, of the oscillating and rotating mechanisni tor the slides; 7

Figs. dand 5 represent plan views 01': the slide frames together with the partscoopen ating with the rotating and oscillating mechanism Fig. 6 represents a cross section of Fig. 4. taken on line 6-6 thereof;

Fig. 7 represents a cross section of Fig. 5 taken on line 7-7 thereof;

Fig. 8 illustrates the application of my construction for window display, the mechanism being incased by the metallic cover A. therefor, the cover having an opening for the protrusion oi the projecting lens which registers with an opening beneath the platform oi shop window, for example, the lens being also in alinelnent with a mirror placed at an angle of approximately e3 and which reflects the picture upon a semi-translucent medium whereby the picture may be seen fronrthe outside of the window, or upon an opaque medium whereby the picture may be seen upon the surface on which it is projected;

Fig. 9 is a detail view of the manner in which the electric bulb beneath the lens may be secured 111' my construction.

In these drawingsl represents themctal lic frame work supporting various moving parts oi. my mechanism, said frame work comprising two pairs of parallel vertical beams 1'1, 1 1", two pairs of parallel cross beams 2 and 2 two pairs of parallel horizontal beams 3 and 3 extending at right angles between the two pairs of vertical beams and l and a pair of parallel horizontal beams 13 intermediate of: the beams 23 and 3. These beams being rigidly screwed. or riveted together constitute the metallic frame and also serve as bearings as will hereinafter appear. A. motor (,5 is supported in the lower part of the frame upon a cross beam secured between the beams 3"-3 and drives the longitudinally extending shaft 4, which shaft is provided with a worm gear 5, which in turn meshes with the teeth of a gear wheel 6 rigidly secured upon a shaft 7 which is journaled in the lower pair of beams 2-l-3". This shaft T also car ries the pinion S rigidly secured thereon, which in turn meshes with the teeth of the gear wheel 9 mounted to rotate about the shaft 10, the said gear wheel 9 actuating the Geneva movement 1 a mounted upon the rotating shaft 9 This rotating shaft 9" carries also a' pair of sprocket wheels 11, the teeth of which engage the links of a pair of continuous chains or slide carriers 12 travelmg in unison with one another. The shafts 7 10 and 9 ma as shown be convenientl mounted in the beams Li -3 as shown in my drawings.

The pair of chains 12 are arranged to travel from the pair of sprocket wheels 11 to the pair of sprocket wheels 13 journaled in the pair of horizontal cross beams 13 and thence to the pair of sprocket wheels 14 journaled in the pair of horizontal beams 3, said several pairs of sprocket wheels being arranged in staggered relation to one another so as to provide for greater chain length than could otherwise be secured. From the pair of sprocket wheels 1% the chains 12-travel across the frame work in a direction longitudinally thereof to a pair of sprocket wheels 15, also journaled in the pair of horizontal beams 3, thence to a pair of sprocket wheels 16 ournaled in the pair of horizontal beams 13, thence to a pair of sprocket wheels 1'7, thence to a pair of sprocket wheels '18, thereafter again to be taken upby the pair of sprocket wheels 11 in the continuous movement of said pair of chains. V

Mounted upon the pair of chains 12 are I a series of frames 19 adapted to carry the slides to be projected. The frames 19 are preferably made of sheet metal and detachable from the chains and are loosely or mova-bly mountedthereonso as to follow the journey over the sprocket wheels without flexing. In Figs. 1 and 5 I have shown these frames 19 as provided with hooks 20 which serve as pivots and engage the links of the chain 12. The frames 19 also are preferably provided with lugs 21 which may be made of pliable metal so as to permit of the insertion or removal of the slides.

It will appear from the foregoing description, that, starting from their engagement with the sprockets 11, the .pair of chains and the series of picture slides are continuous in movement and are preferably arranged to cover a tortuous journey for the purpose of obtaining a greater chain length to enable'a greater number of slides to be carried thereby, within a compact space.

The illumination for the slides is supplied by an electric lamp 2:2 and its connections to a source of electric energy. This lamp 22 may be supported by means of a bracket 28 fastened to one of the horizontal cross beams, as the cross beam 13, and is located beneath the condenser 2i and the projector lens 24.

At the place in which the slides are in position for exposure I provide a mechanism for either rotating or oscillating one or more of them as desired, said mechanism comprising two shafts 25 and 26, the shaft 25 having a rotary motion and the shaft 26 having a. rocking or oscillating motion. These shafts carry means to cooperate with means provided upon the slide frames for rotating or oscillating a slide or one of a pair of superimposed slides. The shaft 2: at its free inner end carries a pinion 27, the teeth of which are adapted to engage with the radially disposed teeth 25) of a supplemental or auxiliary slide frame 28, which is free to revolve in a groove 31 of a plate so, the plate 30 being adapted to lit into the frame 19 on top of the slide carried by said frame 19. The driven end of the rotary shaft 25 is connected by a bclt-and-pulley connection 32, with a pulley 33 carried by the shaft 7 so that with the rotation of the shaft 7 a rotary motion will be transmitted to the shaft 25 and its gear wheel 27 and therethrough to the auxiliary rotating slide frame 28. The mechanism for oscillating. in contradistinction to rotating. a slide or one of a pair of slides comprises the shaft 26, the free inner end of which carries a friction disk 31 to engage a raised radially serrated or roughened surface 35 provided upon an auxiliary slide frame 36 which may be mounted in a plate so similar to the mounting of the auxiliary slide frame 2 lVhen the auxiliary slide frame 36 comes beneath the disk 31 its serrated raised surface will be engaged and actuated thereby. For the purpose of maintaining the friction surface 35 in operative position relative to the disk 31 and to limit the oscillating mo tion of the auxiliary slide frame 36. it is desirable to provide a. stop thei'efor such as the shoulder 36. The rocking movement of the shaft 26 is obtained b emeans of a crank 37 secured to the shaft 26. said crank 37 being actuated by means of a link 3S. connected to a disk 89 on a rotating shaft l0 which is connected by means of a beltand-pulley connection l1 with the rotating shaft 25. i

For further clearness I shall now describe the train of operation of my construction.

The desired number of frames carrying the slides to be exposed are hingedlv mounted upon the pair of chains 12. ()iie or more of these frames may be equi n ed with the auxiliary slide frame 36 or the auxiliarv slide frame 28 or with both. The motor then set into operation and its shaft 1- through the worm gear 5 rotates the gear (3 and the pinion S mounted upon the shaft 7 motion is thereby transmitted to the gear wheel 9 and its Geneva movement 9 and to the sprocket shaft 9 and its pair of sprocket wheels l111. The pair of chains or slide carriers 12 are set in motion aml with them the frames 19 mounted thereon. Such of the slide frames 19 as are not equipped with the auxiliary slide frames 28 or 36 will travel into alinement. with the condenser and the lens without engaging the auxiliary rotating or the oscillating members 27 and get. During the time of exposure of the slide, (the time of exposure being regulated by the Ge:- neva movement) the slide will remain stationary. Assuming the succeeding frame 19 to be equipped with the auxiliary slide holder 28, said holder when it has reached the position for projection will be engaged by the pinion 27, the teeth of which will mesh with. the radial teeth 29 provided upon the auxiliary slide holder 28, thereby rotating the same while at the location of exif such slide be superimposed upon. a stationary slide carried by the frame li), relative motion to the design or picture carried by said frame 19 Wlll be obtained. Assuming the next succeeding slide frame to carry the oscillating auxillary frame SGhavmg the raised friction surface 35, the said frame when advanced to the location of exposure will carry the raised friction surface 35 into operative contact with the friction rocker disk 34:. The rocker disk 34: will transmit to the auxiliary slide holder an oscillating movement during the exposure of the slide carried thereby and if a. pair of superimposed slides be used, one stationary in the frame 19, the other oscillating in the frame 36, a relative movement between the slides will be obtained. Fig. 5 illustrates a slide exhibiting on the stationary slide the form of a person, an arm being omitted, while on the superimposed oscillating slide in the auxiliary film holder the arm and hand are placed in proper relation to said form, the two being so superimposed that the reciprocating movement for theauxiliary film holder will simulate the movement of a per son brushing the teeth. For advertising purposes, for instance, this simulation of movement is particularly effective and is adaptable to every conceivable kind of merchandise or commodity. After the ex posure, as regulated by the Geneva move ment, is completed the next frame will be brought into position and so forth, until all the slides of the series will have been exhibited, when the series will be again repeated by the continuous journey of the chains.

While I have shown the mechanism of my apparatus in a position whereby the picture is projected upwardly, 1t Wlll, of course, be understood that by tilting the mechanism the picture may be projected upon a side wall, in which case the reflector can be dispensed wlth. It Wlll also be understood that my construction may be made with various modifications without departing from the gist of the invention.
